You didn't indicate any special format for your file, so if you're just trying to save data you can just save it in a tab-delimited file which Excel can open directly. You can use the "Write to Spreadsheet File" function to do this. If you save it with the .xls extension then you can double-click the file in Windows Explorer to just open the file directly. That's how I save the files I generate from the testing we do here. No fuss, no muss.
